New, nice and fresh; Telegram is like SMS, but more powerful. You can send messages, photos and videos to people who are in your phone contacts (and have Telegram). You can also create groups. Telegram is cloud-based, decentralized and heavily encrypted. As a result, you can access your messages from several devices and store an unlimited number of photos and videos in the cloud.
And if you like the nitty gritty stuff: Telegram's encryption is based on 256-bit symmetric AES encryption, RSA 2048 encryption and Diffie–Hellman secure key exchange.
